MINOR: Update node label

[jolshan]

After some discussion on why builds were timing out for a month, it seems that this change fe6a827 was incompatible with the jdk image currently used.

Updating the image so builds do not time out.

I think the explanation is that we're triggering a JDK bug. That's worrisome though and we should probably file a JIRA upstream with the JDK version so the contributor can figure out what to do (either have a "known issues" note or fine a workaround).

That's a fair point. I'm struggling to figure out the exact bug but it seems that it was hit on the new java 8 version I tried as well. Not sure why AK was able to handle it fine.

I found that reverting the test here allowed the build to complete. 185d187

I think we still need to update the node label, so I can leave this open, but we don't need to file an issue with the jdk (for now)
